Just needs a bit of a tidy up and onto the other pillar which is a lot worse.

Only one way to cure it and that is to cut it out and replace it with some new metal.

Windscreen Frame

Then onto the windscreen frame. A real pain in the ass, more rust that I hadn't expected. As soon as you put a grinder and rotary wire brush to what looked like a bit of surface rust this happens.

New metal welded in and ground off.

Rot cut out.

Front bulkhead repairs

Still working on the front tub and still finding rot.

This is on the back of the bulkhead, below the parcel shelf. This has rotted through form where the heater mounts on the front of the bulkhead and where all the crap gets in through the fresh air intake mesh. It gets trapped holds all the rain and finally rots through. The front side was a bit fiddlely to repair, but this bit was straight forward.  

A lot of rot was cut out and replaced with new metal. I measured the positions of the brackets before they were removed, so for now I will just tack them in position, until I am happy  that the holes line up with the side rails.
